Accuhaler symptoms and conditions

I have just started my son on Singulair about 1 1/2 weeks . ago. He is also on Allegra plus using the Nasonex. The allergist did warn about all the things that have been reported about this drug. We still decided to try it to see how he responds to it. The number one thing we have noticed is: it has really made a difference in him with his allergies for the good. As in all the things we have heard about behavior issues with others, we have seen an increase in his energy and hyperness but not enough to alarm us yet. We have decided to keep him on it until we see a difference that we feel he is in any kind of danger or anyone else. Hopefully this will not be the case, we all are just getting our exercise which we did prior with him anyways. I hope that a few more positive reports come in, taking any kind of drug you run the risk of side effects. I'm not a fan of taking them but right now they help my son breathe and enjoy being outside where kids should be playing and loving life.
